Ideally I'd like someone to advise me on how to debug the problem, failing that it should be easy enough to recreate. It may well be a hardware issue as these boxes do run very hot, bordering on thermal design limits. >How-To-Repeat: Start compiling a port. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
